Detection stopped being the problem at 6a94b47b. What failed on 2026-09-24 is
that every dot was green and nobody was looking at any of them: at T-2 the
eyes are on Pulsar and the hands are on the LCXL, and neither surface said a
word. So this is attention routing, not checking.
Three principles, then the shape. One source of truth (check-gig --json; no
surface grows its own check). An alert lands on the surface the eyes are
already on, which is a different surface at T-30, T-5 and T-2. And a wizard
is ordered and blocking where a dashboard is neither: one blocker, its fix,
a re-check of that ONE probe because the full gate costs 16 s and a
16-second wait per fix is how a wizard gets skipped.
It never converges on its own. Arming a track, raising a fader and saving are
things only PLN's hands in Ardour can do, and a tool that edits the session
he is performing from is a tool that fights him.
Also records the one alert that earns the right to interrupt a set - Ardour
not recording while Tidal plays - and pins it to the FILES lens, because the
OSC surface claimed arm:false for all 76 minutes it was actually recording.
Three open questions left for PLN rather than answered here: which surface
the T-2 alert lands on, whether an at-my-own-risk skip is acceptable, and
how long the during-set silence window is. The last one needs one rehearsal,
not an opinion.
Retention and the Mix audit are marked done in the belt-and-braces list, and
Tidal 08 is ticked: PLN armed it at 17:38 and the saved session now reads
rec-enable=1 on all twelve.
